Conversion Formula
To convert miles per gallon (mpg) to liters per 100 kilometers, use the formula: liters/100 km = 235.21 / mpg. This works because 1 mile equals 1.60934 km, and 1 gallon equals 3.78541 liters. The constant 235.21 combines these conversions for direct calculation.
For example, with 20 mpg: 235.21 / 20 = 11.76 liters per 100 km, showing how fuel consumption changes with different mpg values. The higher the mpg, the fewer liters used per 100 km.
Conversion Example
- Convert 30 mpg:
- Apply formula: 235.21 / 30
- Result: 7.84 liters per 100 km
- Convert 15 mpg:
- Apply formula: 235.21 / 15
- Result: 15.68 liters per 100 km
- Convert 25 mpg:
- Apply formula: 235.21 / 25
- Result: 9.41 liters per 100 km
- Convert 40 mpg:
- Apply formula: 235.21 / 40
- Result: 5.88 liters per 100 km
- Convert 10 mpg:
